Control of External Devices

TX Inhibit in Busy State (when Squelch is Open)

When transmission is inhibited in the busy state, pressing [SEND]
on the front panel or [PTT] on the microphone does not execute
transmission while this transceiver is busy.
Configure in Advanced Menu [12] "TX Inhibit While
Busy"
Setting Value Off (default)/ On

Reversing the PKS Signal Polarity

Short-circuiting the PKS terminal to GND places this transceiver
in the TX mode. This polarity can be reversed according to the
device to be connected.
Configure in Advanced Menu [11] "PKS Polarity
Reverse"
Setting Value Off (default)/ On
Off: Short-circuiting the PKS terminal of the ACC 2 connector
to GND places this transceiver in the TX mode.
On: Applying a voltage of 3 V to 5 V to the PKS terminal of the
ACC 2 connector places this transceiver in the TX mode.

USB Keying

This function is compatible with PC applications for controlling the
different behaviors including CW keying, RTTY frequency shift and
PTT/SEND (TX/RX switching) using the RTS/DTR signal of the
COM port.
It allows the above behaviors to be assigned to the RTS and DTR
signals of the 2 virtual COM ports (Standard and Enhanced) during
USB connection.
Off: Disabled
Flow Control: Behaves as a hardware flow control signal for
command communication.
CW Keying: Behaves as a CW keying signal.
RTTY Keying: Behaves as an RTTY frequency shift key signal.
PTT: Behaves in the same way as PTT (SEND).
DATA SEND: Behaves in the same way as DATA SEND (PKS).
Configure in Advanced Menu [17] "Virtual Standard
COM Port – RTS"
Flow Control (default)/ CW Keying/ RTTY
Setting Value
Keying/ PTT/ DATA SEND
Configure in Advanced Menu [18] "Virtual Standard
COM Port – DTR", [19] "Virtual Enhanced COM Port
– RTS" or [20] "Virtual Enhanced COM Port – DTR"
Off (default)/ CW Keying/ RTTY Keying/ PTT/

To switch the COM port or exit the application in the PC
●
application for performing transmission on the
transceiver using the USB keying function, be sure to
complete the transmission before doing so. Otherwise
transmission error may occur on the transceiver.
If the COM port for outputting the USB keying signal is
●
not selected (open) in the PC application that is using the
USB keying function, the signal for USB keying may be
accidentally transmitted. Press [
of this transceiver or disable the USB keying function
temporarily until the preparation on the PC application is
completed.
"RTTY Keying" can only be configured for 1 out of the 4
●
signals (duplicate configuration is not allowed).
When this menu is configured to "RTTY Keying" (during
●
RTTY operation via USB keying), RTK of the ACC 2
connector will be disabled.
Please use the latest virtual COM port driver.

Decoded Character Output

This function outputs characters decoded by the built-in decoder
of CW/ RTTY/ PSK from the virtual COM port (Enhanced). The
baud rate is also variable.

Turning ON/OFF Decoded Character Output

Configure in Menu [7-03] "Decoded Character
Output"
Setting Value Off (default)/ On
Configuring the Baud Rate of the Virtual COM
(Enhanced) Connector
Configure in Menu [7-02] "Baud Rate (Virtual
Enhanced COM)"
